Hab. Conception.—This does not differ from tlie larger state of C. hirstita found in our country, and
which Continental Botanists have called C. sylvatica: and it equally appears to be the C. flaccida of
Chamisso and Schlechtendal, which the former Natunalist gathered also in Chili.

Hab. Conception.—In habit this plant is certainly allied to C. pratensis, and especially to that var.
with narrow leaflets which is described in the Flora Boreali-Americaua, under the var. angustifolia : but
its leaflets, and in particular those of the root-leaves, are still narrower, the flowers are smaller, and, in
the extremely attenuated beak to the pods, it differs from all the species we ai-e acquainted with.

Hab. Valparaiso.—The specimens in the collection are extremely small, scarcely two inches high, erect
and simple. Those we have from the same country, gathered by Mr. Bridges, are a foot lotg, much
branched, especially from the base. In both we find all the essential characters of the L . I
of Desvaux, who justly observes that it is nearly allied to L. bonariense.
